LIQUID-DISCHARGING DE VIGE Specification 01 Letters Patent.

Patented Feb. 9, 1909.

Application filedJuly 22, 1908. Serial No. 444,710.

T 0 all whom it may concern:

Be it known that I, WILLIAM C. MORRILL, a citizen of the United States,and a resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Liquid-Discharging Devices, of which the following is aspeclfication.

The invention relates to that ty e of liquid discharging devices whichdisc iarges the liquid in a predetermined quantity, of which a full,clear and exact description will be given hereinafter. l

The invention consists of the combination of certain mechanical elementsadapted to work in unison one with the other in a mannor that willenable it to discharge liquids in a predetermined uantity when operated,all of which Will be ully described and pointed out in the claimhereinafter.

Figure 1 is a lon itudinal vertical section of the discharging eviceshowing the man ner in which it is mounted u on the reservoir. Fig. 2 isa plan of the ischarging device. Fig. 3 is a longitudinalverticalscction of a modified form of the dischargin device in which theguide rod is dispensed with. Fig. 4 is a plan of Fig. 3. p

Similar letters refer to similar arts throughout the drawings in whichthe 0 ambered body a. is shown mounted upon the reservoir 0. a part ofwhich is shown in section in Fig. 1. The up er exterior circumferentialsurface of the ody a. is provided with screw threads terminatin at theex treme upper end of the said he y 0. Upon the top of the said body a.is mounted the internall screw threaded doubly perforated cap 0. helower end of the aforesaid screw threads receives the lock nut b.which,when screwed up tightly, will exert sufficient pressure upon thecompressible washer t. to make a liquld tight joint between theperforated cap 0. and the wall of the reservoir.

he body a. is provided with the chamber 2. having the feed channel (1.ending at q. openin into it. There is within the cham ber e. t e pistonf. which is capable of bein operated reciprocally and which is providedwith the vertically arranged guide rod 9., the upper end of the latterengaging with the perforation k. made in the cap a. and serving as aguide for the aforesaid rod.- The cap 0. is provided with thepermanently 0 en port 1. Connected with and dependin rom the bottom ofthe piston f. is arrange the operatin rod h. which travels through aport in the ottom of the chambered body a. This operating rod h. isprovided with the chamfered recess 2'. and the push knob or button 1).The iston is provided with a frustuni base whic 1 when in its normalposition, seats itself into a liable washer m. the ,conical action ofwhich has been purposely made a little smaller than the frustum base ofthe iston so that the frustuin base may make or itself a perfect fittingseat and act as a conical valve. The length of the chamfcr is soproportioned that the rod below it completely closes up the port throughwhich the rod passes at the'instant, or immediately before,'the fiatbase of the piston, on its upward stroke,reaches the bottom of thechanne (1.

In Fi 3 is shown a modification of Fi 1. In t is figure the istonf isshown void of the guide rod 9. 1 1 also shows the screw cap 0 providedwith a sin le perforation Z and an enlarged spring n p aced within thechamber e It will be obvious that the liquid will enter at the open portZ thence to the feed channel d, in the same manner as it does in thedevice shown in Fig. 1.

I do not wish to confine myself strictly to -the forms shown anddescribed as it. is obvious that many modifications may be employedwithout departing from the spirit of my invention.

Mode of operation: I shall describe the apparatus when used for li uidsoap. When the reservoir 0. which at t 1e to may be air tight, open, orpartially close shall have been filled with liquid soap, it will then beready for use. It will be obvious that there will always be opencommunication between the reservoir 0. and the feed channel d. by meansof the permanently 0 en port Z. When desirous of extracting the iquidsoap from the reservoir 0. the operator simply places the palm of hishand beneath the push knob or button 1). and presses same upward as faras it will go. This operation carries the lower flat surface of thepiston f. above the base q. of the feed channel (1. sucking the air fromthe outside in through the lower port and up through the feed channelinto the s ace immediately above the level of the liquid soap,. thusmaintaining the equilibrium of the atmospheric ressure between theinside and outside of t e reservoir. As the air ascends the liquid soapflows down intothe space between the piston and the r that valve seat,the latter of which, in this case, is formed of the pliable disk m. Theport at the bottom of the chambered body and beneath the valve seat willhave been closed by low t e chamfer i. hen t 1e upward pressure shallhave been removed from the operating rod, the spring will carry thepiston f. back to its normal position. It will be obvious that thecommunication of the feed channel (1. will have been cut oil from thatpart of the chamber e. lying beneath the piston at the instant or beforethe lower end of the chamfer of the operating rod shall have reached theexterior. W hen the lower end of the chamfer reaches the exterior thepressure of the piston forces out and discharges through the partiallyopen port into the hand of the o erator the amount of liquid soapcontains between the base of the piston and the bottom of the chamber.At the end of the downward stroke the frustum base of the piston seatsitself into the conical hole of the washer, forming a conical valvewhich shuts off completely. This operation may be repeated at will, theoperator getting the same amount of soap at each operation.

It will be obvious that there can never be a ortion of the o crating rodh. lying be continuous open communication between the reservoir 0. andthe exterior through the port at the bottom of the chambered body a. andthat therefore, at no osition of the piston, will a steady stream oisoap flow, but, on the contrary, onl a predetermined quantity will bedischarge and a complete cycle Will have capable of being operatedreciprocally within the aforesaid chamber said piston also formmg avalve, and a chamfered rod depending from the aforesaid piston.
